The Oxford Internet Institute chose to study Michigan due to its status as a battleground state. (President Donald Trump wound up winning Michigan by just 10,704 votes.) Researchers reviewed 138,686 tweets from self-described Michigan users, filtering by political hash tags like #MakeAmericaGreatAgain and #DrainTheSwamp.

Of the 24,783 tweets that included links, 6,469 cited content that researchers deemed "propaganda" or "dubious" — coming from sites like Breitbart and InfoWars.

By comparison, only 6,408 tweets included links from professional news companies.

"This isn’t the first election cycle where people have made stuff up about the government and politicians and candidates," Dave Dulio, chairman of the Oakland University political science department, told The Detroit News. "It maybe has reached a peak, let’s hope, during this past election cycle."

The Detroit News story also notes that this fall the University of Michigan will offer a "fake news" media literacy course.
